The GPU2 client loads a whole CPU core, but it seems to be independent from CPU speed. I clocked the CPU up to 3.2GHz and down to 1GHz, both shows nearly the same time per %

3.2GHz 17sec per %
1GHz 17.5sec per %

I decided to downclock and undervolt the processor. A SMP client at the same time cuts the ppd coming from the GPU2 client too much and needs more power

I've got p5001 and p5002 till now, each of them is only worth 98 points, but nearly 50 units a day leads to 4700 ppd and more
Lets see how this theory works in practice. You can follow my stats at eoc, the one GPU2 client is the only one that folds for me.

@ccperf721p: What time per % do you get? Is it a old 8800GTS with 320/640MB or a new 512MB?

Thanks, I will load them up tonight. I did a little testing with the GPU2 and 5 series smp client running and it actually surprised me that the GPU ran the same and the smp only took a 30 sec per % hit. Might be able to throw a 6K per day average down until I have to unplug my rig to move.

They don't recommend using the GPU client and the CPU SMP client concurrently, not sure of the exact rationale but it isn't stable that way.

Instead, they say it's better to use the GPU client and a standard console CPU client(not SMP).

@cc, gedon; should we create a thread only for the GPU client, like the one we have for SMP? I think it's gonna be important to some, and we can keep the info and experiences in one place. Whaddya think?

I got it to work first time. Had to hack the 177 drivers to install though. Had a good lock up first time with SMP running. Was ok after a restart. I guess we will see what happens. I will try it both in dual view and in SLI to see if it make a difference in performance or stability.

Yup. From what I'm reading, you can't run the GPU and SMP clients together on a dual-core cpu. The GPU client will use pretty much all of one core, and the SMP has to have both to function.

However, there are workarounds being invented to help users run this combination on Quads. For now, the clients don't use all of the CPU as yet on their own, so it can be done. That being said, it won't last forever, so when they release another client that scales better you will have to adjust/abandon your scheme.

This is the thread you need to do your homework, y'all, so check it out:

OK, no one has done it yet so I will...
Here's a new thread to post all of your experiences with the new GPU2 beta client. I think that many folks with graphics cards supporting CUDA will be interested.

First and before you do anything else, LOOK OVER THE FAQ: Folding@home - FAQ-NVIDIA
Lots of important things in there that you'll need to know if you do anything beyond run the installer and run it.

Known bugs:
It's a beta, and yes we meant that, not like Google but like software engineers - expect glitches and updates. The main thing is that the viewer will not work, as we're in the middle of changing how the live coordinates get to the viewer. Other then that, visit our nVidia beta Forum to see what's happening.

@Daniel~, Gizmo, Aedan:
Do you have the awesome power to move the last dozen posts or so [relative to the GPU client]from the other thread ["AOA is losing ground"] into here? There's some good info there already, maybe we can keep it together.

to the end of that thread(about 15 posts) can be moved to this thread that we are in right now, "GPU2 client for nVidia". That would be great. I think this will be a very active thread in the near future.

As for getting out of beta, Pande operates in one of two modes: 1) we're working on it; and 2) It will be ready when it's ready.

Since moving to the 177 drivers it has really picked up a bunch. I have also been running the smp client along with it, so far no issues. Note Will not work on a dual core as the gpu client will use one core itself and causes strange results. It does however run on quad without much of performance penalty

I have noticed the same. I am at this time running SMP and GPU. I can't do it in SLI. It is bad....

But I am not in SLI most of the time.

I feel bad for missing this. I have been buried at work and been doing several side jobs after. I get time to post and am lucky if I actually have a clue what I am posting about. i will spend a little time on this and help Bob and Cliff get this sorted and add it to the front page in the FAH section.
